Fenix 7 series breaking changes in firmware 11.28 for createBufferedBitmap and SDK 4.2.1

The behaviour for createBufferedBitmap changed and the rendering in the watch face app doesn't work as expected and described in the documentation.

Previous firmware versions work fine. It seems that the transparent color is not available anymore and the color palette option handling changed in SDK 4.2.1.

The rendering logic in the watch face was stable since at least one year and the color palette do not provide all colors as expected. This leads to a false rendering.

In addition the Simulator for all Fenix 7 series devices always draw a black background when the transparent color is used as background color. This is also changed in SDK 4.2.1.

Please fix, thanks.
